Maintenance; Cleaning The Treadmill; Adjusting The Belt Tension; Lubricating The Running Deck - Tunturi J 440 Owner's Manual

NOTE! Do not turn more than 1/8 at the time as
already very small adjustments effect the
alignment.
4. If the belt remains centralised the adjustment is
correct. If not, continue to make small
adjustments as above, checking for centralisation
each time until the belt is correctly aligned.
If the belt is allowed run across to one side for long periods
the edges of the belt may be damaged and the treadmill may
not continue to operate correctly. Any damage to the belt
caused by the lack of necessary adjustment will not be
covered by the warranty.

ADJUSTING THE BELT TENSION

NOTE! The belt must be tensioned if it begins to slip on the
rollers. In normal use, however, keep the belt as loose as
possible!
The belt tension is adjusted by turning the same screws as
used for aligning the running belt.
1. Turn the power switch on and increase the
treadmill's speed to 5 km/h (3 mph).
2. Turn both adjustment screws an equal amount,
approximately 1/8 turn clockwise.
3. Try to slow the belt down by holding onto the
handrails and braking as you walk (as if you were
walking downhill). NOTE! When braking heavily
the belt may slip.
4. If the belt slips, turn another 1/8 turn and repeat
the test.

MAINTENANCE

We strongly recommend that a periodic maintenance
schedule is adhered to. If you wish to have the maintenance
carried out by a trained technician please contact your local
Tunturi dealer for details of service available and charges.
Check from time to time that all fasteners are properly tight-
ened and wiring is in place. To avoid damaging fasteners, do
not overtighten.
CLEANING AND
INSPECTING THE RUNNING BELT
Turn the unit off and unplug the electrical cord from the wall
outlet and from the treadmill. Carefully turn the treadmill on
its side. Wipe off the inside of the running belt using a harsh
brush. Do not use solvents.
Rotate the running belt carefully by hand to clean the entire
inside face. Loosen the belt adjusting screws at the back of
the treadmill, if necessary. Return the treadmill into the
upright position.
If running belt edges are frayed, check the running belt
alignment. If seams are splitting contact your local Tunturi
representative.

CLEANING THE TREADMILL

Wipe the treadmill surfaces, especially the handlebars and
meter from dust with a damp cloth or towel. Do not use
solvents.
Use a small vacuum nozzle to carefully vacuum around all
visible components (belt, running deck, side rails etc.). By
supporting the device on one of the side rails you can also
vacuum it from below. Vacuum also from inside the motor
hood.
Clean the rollers once a year as follows: Loosen the adjusting
bolts and wipe the rollers with a harsh brush. Tighten the
tension adjustment bolts. Check that the running belt is
aligned and centered on the treadmill bed.

LUBRICATING THE RUNNING DECK

Lubrication is the most important service activity for the
treadmill. This is absolutely essential, if the friction of the
running deck increases noticeably or the motor begins to
heat up. Ensure after every 50 hours of use that both the belt
and the running deck are moist with lubricant. Insufficient
lubrication will cause the belt, running deck and motor to
wear out and break.
The need for relubrication depends to a great extent on the
running styles and weight of the user: heavy user weight and
slow speed put particular strain on the device and therefore
demand greater lubrication. Use only T-Lube lubricant to
lubricate the treadmill. Contact your local Tunturi dealer for
further supplies of T-Lube.
NOTE! The device must under no circumstances be
lubricated with silicone!
1. Let the treadmill run at 5 km/h (3 mph).
2. Spray T-Lube directly to the underside of the running
belt for 5 seconds; the amount corresponds to 10 ml.
3. Ensure that a strip of about 20 cm / 8" wide on the
underside of the running belt becomes moist with
T-Lube along its whole length. The treadmill is
instantly ready for use.
